Severe pediatric epilepsy seizures are characterized by sudden loss of consciousness, followed by intense stiffness and then convulsive, severe pain. This is often accompanied by shouting, blue or purple face, urinary incontinence, tongue bite, vomiting froth or blood foam, dilated pupils, and after lasting for tens of seconds or minutes, the severe pain recurs naturally and stops. After falling into a coma, there may be short-term dizziness, irritability, fatigue, and an inability to recall the process of recurrence. If the recurrence continues without interruption and the child remains in a coma, it is known as a persistent status epilepticus, which often poses a risk to life.
